Fresh Natty installation gives me some GRUB error messages on startup:

error: file not found.
error: file not found.
error: no suitable mode found.
error: no video mode activated.
error: file not found.
error: file not found.

Regardless of these errors it boots up. It probably is somewhat related to my previous question as I specified the partitions manually and ended up in the GRUB recovery console. To solve that I booted from Live CD and ran:

sudo mount /dev/sda3 /mnt
sudo mount /dev/sda1 /mnt/boot
sudo grub-install --root-directory=/mnt /dev/sda

Do those errors matter? How to get rid of them?

All that was required to fix it was runningsudo update-grub in terminal.
